I see your reasoning, but the Super 530 was explicitly specified for the ACF in the requirement and test missiles would have been available from the start of flight testing. It's unlikely the radar would have supported the older R.530, and for aerodynamic testing you'd use a inert round of the Super 530 shape.

Its still a nice drawing though

Design of the Super 530 began in 1968, with the start of development in 1971. The first firing of a controlled mock-up missile took place in February 1973, following ramp tests in 1971 and flight trials of the AD26 homing head in 1972. In July 1973, drop trials were carried out, followed by aircraft carriage and aerodynamic trials in the first half of 1974.

Development and evaluation trials by the Centre d’Experience Aeriennes Militaires (CEAM) continued from 1974 through 1977 and included live firings. The first fully guided firing took place in 1975, when a missile fired from a Vautour flying at Mach 0.7 at a height of 11,000 meters (roughly 36,000 ft) successfully intercepted a target drone flying at Mach 1.6 at a height of 18,000 meters (approximately 59,000 ft). The first firing from a Mirage F1 took place in 1976; following the successful conclusion of the trials, a production contract was signed in late 1977.
